Skyline Tutor (oz10456)

About this Plan

Skyline Tutor. Cabin sport model for free flight or single channel radio control.

Quote: "The Skyline Tutor has been designed as a semi-scale cabin model and when powered by engines of about 1 cc achieves a realistic scale flying speed. The prototype has been flown with success powered by a Mills .75 but it proved rather under-powered for take-off, thus necessitating hand launching. With engines of 1 cc successful ROG flights can be made.

Fuselage. The fuselage is constructed basically of 3/16 in sq longerons and spacers, 1/16 in sheet being used on the sides from the nose block to former F4. Celulloid covering is used on both, top and bottom of cabin, so that it is possible to see inside the fuselage should radio be fitted.

Nose Block.The nose block is designed to knock off, being located by two dowels and held in position by rubber bands attached to two hooks. This facilitates complete removal for engine servicing and reduces the risk of damage in the event of a heavy landing. It is built up from 1/4 in laminated soft balsa and sanded to shape. The engine bearers arc glued to the sides with Croid universal glue, whilst the oval air-intakes are cut out of the ye in. sheet covering. Behind arc cemented in position diagonally, 116 in. balsa slats to represent radiator grilles. A neoprene overflow pipe is cemented to the underside and this carries away all surplus fuel thus leaving the airframe clean.

Undercarriage. This is very light, strong, and simple to make. It is braced where shown by piano wire soldered to brass fittings located in hardwood blocks, which are cemented to B1 and U1. Tin keepers are soldered to the legs, upon which the balsa fairings are sandwiched together and sanded to a streamline section. These legs may then be bound with Cellotape before covering with paper, which adds greatly to their strength.

Wings. The wings also, are designed to knock off, and are practically unbreakable under normal flying conditions. They are secured to the centre section by two rubber bands fitted to wire hooks on the main spar. The bands are pulled through the hatch by means of a hook formed on a length of wire, the wing struts are then hooked on to the brass fittings..."
